Box breathing and 4-7-8 breathing are the two patterns everyone recommends, and they're often listed side by side as if they were the same thing. They're not. One keeps you steady; the other helps you let go. Here's how they differ, what the research actually shows, and which to reach for when.
Use box breathing (in 4, hold 4, out 4, hold 4) to steady yourself in the moment, especially with your eyes open: before a meeting, during a stressful call. Use 4-7-8 (in 4, hold 7, out 8) to wind down, especially at night, because its long out-breath is the relaxing part. No study has compared the two directly, so the best one is the one you'll actually do.
The Two Patterns Side by Side
| Box breathing | 4-7-8 breathing | |
|---|---|---|
| Counts | In 4, hold 4, out 4, hold 4 | In 4, hold 7, out 8 |
| Out-breath vs in-breath | Equal | Twice as long |
| One round | About 16 seconds | About 19 seconds |
| Typical session | 3 to 4 rounds | 4 rounds |
| Feels like | Steadying, focusing | Slowing down, letting go |
| Best moment | Before or during something stressful | Winding down, before sleep |
| Eyes open? | Easy | Easier with eyes closed |
| Hardest part | Keeping the rhythm even | The seven-count hold |
Box breathing is also called square or equal breathing, and is often described as a technique used by US Navy SEALs to stay calm under pressure (Cleveland Clinic). 4-7-8 was popularised by the integrative-medicine doctor Andrew Weil (Andrew Weil Center for Integrative Medicine). Our guide to 4-7-8 breathing goes into it step by step.
What the Research Actually Shows
Honestly, not much that settles it. There's no published study comparing box breathing and 4-7-8 head to head, and most breathing research is small.
The closest is a 2023 randomised study in which people did five minutes a day of one of three breathing exercises, or mindfulness meditation, for a month. Breathwork improved mood and lowered breathing rate more than meditation, and the clearest effect came from cyclic sighing, a pattern built around long, slow exhales (Balban et al., 2023). Box breathing was one of the breathing exercises tested; 4-7-8 wasn't. What it does suggest is that the long exhale, which 4-7-8 is built around, is a good thing to aim for when you want to calm down.
For 4-7-8 itself, a small 2022 study of healthy young adults found that heart rate and systolic blood pressure dropped straight after a few sets of 4-7-8 breathing, whether or not people had slept well (Vierra et al., 2022). That's a real, immediate calming effect, but it's one small study measuring minutes, not months, and neither pattern is a treatment for anxiety or insomnia.
For Falling Asleep
4-7-8 is usually the better fit. The long out-breath is the relaxing part, the pattern ends on a slow breath out, and it's easy to do lying down with your eyes closed. Four rounds, then let your breathing go back to its own rhythm. If thoughts keep pulling you back, our guide to stopping overthinking at night adds two things that help.
For a Stressful Moment
Box breathing is easier here. The even counts are simple to hold in your head while your eyes are open and something is happening around you, and nobody can tell you're doing it. A few rounds before a presentation, a difficult call or a hard conversation is enough to take the edge off. If you have a minute alone afterwards, a few slow 4-7-8 breaths can help you come down.
If Holding Your Breath Feels Bad
Both patterns include holds, and for some people holding the breath brings on light-headedness or a sense of panic. You can drop the holds entirely. The NHS's breathing exercise for stress is simply a gentle five-count in and five-count out, with no hold (NHS), and making the out-breath a little longer than the in-breath keeps most of what both patterns offer. If you have a heart or lung condition, are pregnant, or breath-holding has triggered panic before, check with a doctor first.
How to Try Each One Tonight
Box breathing
- Breathe out slowly until your lungs feel empty.
- Breathe in through your nose for 4.
- Hold for 4.
- Breathe out for 4.
- Hold for 4, then start again. Three or four rounds is enough.
4-7-8 breathing
- Rest the tip of your tongue behind your upper front teeth and breathe out fully through your mouth.
- Breathe in through your nose for 4.
- Hold for 7.
- Breathe out through your mouth, with a soft whoosh, for 8.
- That's one round. Do four.
If counting is the hard part, our free 4-7-8 breathing timer counts each phase for you, and has a no-hold option. Gentle, our iPhone app, guides 4-7-8 rather than box breathing, because its long exhale suits the moments the app is for: winding down and hard evenings.
Let Gentle do the counting
If you'd like the counting done for you at bedtime, Gentle guides 4-7-8 and pairs it with a kind line:
"This feeling is loud, but it isn't permanent."
"I don't need to solve everything tonight."
Gentle is a free iPhone app that sends short, kind affirmations like these at the hours you choose and keeps one on your Lock Screen. No account needed; an optional Premium subscription unlocks all themes, topic choice and unlimited breathing.

Frequently Asked Questions
Is 4-7-8 or box breathing better for anxiety?
Either can help in the moment; there's no head-to-head study. Box breathing is easier to do discreetly with your eyes open. 4-7-8 has a long out-breath, and exhale-focused breathing did especially well in a 2023 study, but 4-7-8 itself wasn't tested in it.
Which is better for sleep?
Most people find 4-7-8 easier to fall asleep with, because the long exhale is relaxing and the pattern ends on a slow breath out. If the seven-count hold is uncomfortable, a gentle breath with a longer exhale and no hold works too.
Can I combine them?
There's no need. Pick one for the moment you're in: box for steadying yourself before something, 4-7-8 or a long exhale for winding down.
Why do Navy SEALs use box breathing?
Box breathing is often described as a technique used by US Navy SEALs to stay calm under pressure (Cleveland Clinic). Its even counts are easy to remember and to do with your eyes open, which suits high-stress, keep-going situations.
What if holding my breath makes me feel worse?
Drop the holds. Breathing in for a few counts and out for a few counts longer, with no hold, keeps most of the calming effect. Stop any breathing exercise that makes you feel unwell.
